5 / 801 results- Do you want finasteride to penetrate better? The ideal solvent to maximize its effect. Formulation sources describe propylene glycol and microemulsion vehicles as increasing how much topical finasteride crosses the skin, but better penetration has not been shown to mean better hair results, and it also raises systemic exposure. The vehicle and strength are decisions for a prescriber or compounding pharmacist.

research Relative Influence of Ethanol and Propylene Glycol Cosolvents on Deposition of Minoxidil into the Skin
This study found that increasing the proportion of ethanol in minoxidil formulations improved skin penetration in both in vitro and in vivo tests on mice.
research Skin deposition and permeation of finasteridein vitro: effects of propylene glycol, ethanol and sodium lauryl sulfate
In this study, the researchers reported that while both propylene glycol and sodium lauryl sulfate enhanced finasteride's skin deposition, ethanol was the only effective enhancer of finasteride's permeation through the skin.
research Penetration of Minoxidil from Ethanol/Propylene Glycol Solutions: Effect of Application Volume and Occlusion
This study found that minoxidil penetration through the skin increased with higher ethanol content and occlusion, with the highest penetration observed at 90% ethanol.
research New ethanol and propylene glycol free gel formulations containing a minoxidil-methyl-β-cyclodextrin complex as promising tools for alopecia treatment
This study evaluated new aqueous gel formulations of minoxidil without irritants and found that the calcium alginate gel showed the best performance in terms of drug release and skin permeation.
research Comparison of Topical Minoxidil 5% in Ethanol Plus Propylene Glycol Versus Minoxidil 5% in Ethanol Alone in Treatment of Women With Female Pattern Hair Loss

5 / 343 resultscommunity The best Ethanol/Propylene Glycol ratio for home made topical finasteride?
The conversation discusses the best ethanol and propylene glycol ratio for homemade topical finasteride, with a focus on absorption and drying issues. The user shares their experience using a 50% propylene glycol, 30% ethanol, and 20% water solution, and considers adjusting the ethanol content for better results.
community Making topical finasteride with ethanol + propylene glycol vs mixing it with topical minoxidil
The conversation discusses two methods for making topical finasteride: using ethanol and propylene glycol or mixing it with topical minoxidil. The focus is on solubility and absorption, with a suggestion to crush pills finely and possibly mix with minoxidil at a slightly elevated temperature.
community Enlighten me about the role of ethanol and PG in topical solutions, where the ideal ratio of the two is, and why?
The conversation discusses the use of ethanol and propylene glycol (PG) in topical solutions for hair loss treatments, specifically Minoxidil. The user dislikes the texture of PG and questions the ideal ratio and necessity of PG in these solutions.
community The minoxidil product I brought only has ethanol and minoxidil in it and no other ingredients. Will this be absorbed into the scalp?
A minoxidil solution with only ethanol and minoxidil may not be properly absorbed without additional ingredients like propylene glycol or vegetable glycerin. It's suggested to use a reputable brand and test the product for authenticity.
community Are we underestimating systemic absorption with homemade/generic Topical Fin? (HPCH vs. PG/Ethanol formulations)
Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.
